The Mayweather vs. McGregor card takes place at the T-Mobile Arena
in Las Vegas on Aug. 26 and will be available via pay-per-view for
$89.95 in standard definition and $99.95 in high definition.

Cleverly last appeared in October, when he stopped Juergen Braehmer
in the sixth frame to capture the WBA strap in Germany. Jack,
meanwhile, is coming off a majority draw against James DeGale in a
middleweight championship unification bout.

"This is a fight I have wanted ever since Badou Jack moved to light
heavyweight and I'm delighted to fight in Vegas on an event like
this," Cleverly said.

Added Jack: "I'm thankful for this opportunity and I'm excited
about getting another shot at a world title. To be a part of this
event and fighting on this card is historic. Nothing beats it. I'm
excited to get back in the ring. I'm getting ready to take that
belt, and win a title in my second weight class.”

Davis will be making his second title defense after winning the
belt with a seventh-round knockout of Jose Pedraza and retaining it
with a third-round stoppage of Liam Walsh
on May 20. Fonseca, meanwhile, will be fighting in the United
States for the first time in his professional career.

"I'm really excited to fight as the co-main event on the biggest
card in combat sports history," Davis said. "I plan to put on a
great show for everyone in attendance in Las Vegas and for those
who purchase the pay-per-view. I want to thank my team for this
incredible opportunity. I'm ready for Floyd Mayweather to pass his
torch to me. To my fans, I appreciate all of you. Support me and
I'll fight for you.”
